Introducing Yoru (ヨル)

Yoru is Ikuto's cat-like Guardian Character and represents Ikuto's desire to be free. Yoru often goes out by himself and enjoys causing trouble for the Guardians and their Guardian Characters for fun. When Ikuto and Yoru undergo a Character Transformation, they become Black Lynx. Yoru is hysterical when Ikuto does the Death Rebel Character Transformation in chapter 31. Lately, he also can't track Ikuto, because the hypnotizing tuning fork confuses him. Later on, when Amu and Tadase find Ikuto being controlled by Easter, Yoru takes the Dumpty Key and gives it to Amu. In chapter 38, he along with the black egg, combine powers with Ikuto to become Seven Seas Treasure. In chapter 46, Amu finds a dazed Yoru in the Eggs' Cradle. He and Amu fall out of the Egg's cradle and see Ikuto. In chapter 48, when Yoru sees how happy Ikuto is, he comments him for having become a "true alley cat", and goes back to being a heart's egg inside of Ikuto. In the anime television series, Yoru is voiced by Miyuki Sawashiro
